[jira] [Created] (CASSANDRA-15772) DOC - Improve tpstats documentation

Mark Curtis created CASSANDRA-15772:
---------------------------------------

             Summary: DOC - Improve tpstats documentation
                 Key: CASSANDRA-15772
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-15772
             Project: Cassandra
          Issue Type: Improvement
          Components: Documentation/Website
            Reporter: Mark Curtis


h2. Background

The docs for {{nodetool tpstats}} gives the user a good overview of the correct command format, but lack an explanation of the message types.

As of Cassandra4.0 and CASSANDRA-15066 the Message types have expanded a lot so this becomes quite overwhelming (particularly for new users).

I'd propose we offer a simple explanation of these grouping them into logical groups (see CASSANDRA-15771 which I opened for the formatting output). 

The github code for the {{Verb.java}} class does give the user some idea of what these are but not everyone will go looking for that.

Example
